This paper describes the final phase of testing and evaluation of the second stage monometallic water-cooled nozzles for the Department of Energy-funded High-Temperature Turbine Technology (HTTT) program. Earlier papers described the materials and process development work and the fabrication and initial testing of these nozzles. The additional testing of these nozzles in a static hot-gas path development test stand is described, and the results of this testing are discussed in terms of the component design goals. Evaluation of these nozzles after testing, including nondestructive and destructive examination is described in detail.
